Definitions

• the present invention generally relates to a camera lens attachment, and more particularly to a lens attachment assembly which provides for the convenient use and transport of filters, lens assemblies, protective lens covers, and variable position sunshades.
• a sunshade must be capable of being positioned at a desired angle and orientation respective to the lens.
• the lens attachment of the present invention provides for a sunshade to be positioned selectively about the perimeter of the lens, and at the desired angle relative to the lens.
• the lens attachment of the present invention provides a combination of these multiple elements in a convenient arrangement which can be removably coupled to the camera body and unfolded in various positions when a particular element is needed for use.
• the lens attachment of the present invention may be fitted with additional sunshade components.
• sunshades may be coupled to the attachment frame in order to permit rotation and adjustment for any situation.
• the integral lens attachment device of the present invention comprises three primary elements. First, a frame element, incorporating a threaded adapter ring for mounting to the lens of a video or still camera. Second, a lens housing for providing an additional lens, filter, or other such attachment. And third, a cover component which serves dual function as both a protective lens cover and a variable position sunshade.
• the lens housing and the cover component are hinged to the rim of the frame element. Additional sunshade components could also be separately hinged to the frame at various positions.
• the device cover and lens housing may be pivotably mounted to the rim of the frame element with hinge couplings.
• the frame element may be attached to the end of a camera lens by the threaded adapter ring. The position of the frame relative to the adapter ring is adjustable.
• the frame element may be rotated to transport the lens cover and sunshades to another position around the periphery of the lens.
• the frame element may be provided with at least one locking notch on its periphery. Such notches enable the frame to securely lock onto the camera lens adaptor ring.
• small magnets may be added at various positions along the perimeters of the device cover (or sunshade) , the frame element, and the lens housing. The presence of such magnets will aid in providing the ability for the sunshade and lens housing to remain in the desired opened or closed position.
• the additional sunshade components may be outfitted with panels that may be extended in order to increase the effective size and coverage of the sunshades.
• panels may be coupled to the sunshades to make them extendable.
• the panels may be connected to the sunshades by way of pivot pins. Retaining pins may protrude from the sunshades through tracks in the panels in order to hold and guide the panels along their path.
• FIG. 1 is a front view of the lens attachment of the present invention, with the lens cover component in the fully closed position;
• FIG. 2 is a rear view of the present invention in the closed position
• FIG. 3 is a side cutaway view of the present invention in the closed position
• FIG. 4 is a side cutaway view of the present invention with the lens housing in the closed position, and the lens cover component in the open, or sunshade, position;
• FIG. 5 is a side cutaway view of the present invention with the lens housing in contact with the lens cover component in the open position;
• FIG. 6 is a side cutaway view of the present invention with the lens cover component in the open position and the lens housing in an open position located between the lens cover component and the frame element.
• FIG. 7 is a perspective view of the present invention configured with additional sunshade components employing extendable panels for added performance.
• the lens attachment 5 of the present invention may be secured to the lens of a camera using threaded adaptor ring 90.
• Adaptor ring 90 may be secured to the lens of a camera using threaded adaptor ring 90.
• Adaptor ring 90 may be threaded onto the attachment ring which is commonly provided at the terminus of camera lenses.
• Adaptor ring 90 is connected to frame element 20, which may be rotated relative to adaptor ring 90.
• Locking notches 70 seen in FIG. 2, may be formed integral to adaptor ring 90, to assist in locking the present lens attachment assembly to a camera lens.
• the primary elements of the lens attachment 5 are the frame 20, the lens housing 30, and the device cover 10.
• Frame 20 The primary elements of the lens attachment 5 are the frame 20, the lens housing 30, and the device cover 10.
• FIG. 1 shows pin 80 hinges device cover 10 and lens housing 30 to frame 20, in order that device cover 10 and lens housing 30 may be flipped up and out of the way of the camera lens.
• Lens housing 30 comprises retaining ring 40 for securing lens element 50.
• Magnetic pieces 60 may be incorporated into the design of device cover 10, lens housing 30, and frame 20 in order to assist in maintaining the lens attachment in the desired open or closed positions.
• FIG. 3 shows the lens attachment of the present invention in its fully closed position, with both lens housing 30 and device cover 10 in position to cover the camera lens (not shown) . In this closed position, device cover 10 protects the camera lens from dirt or other damage.
• FIG. 3 shows the lens attachment of the present invention in its fully closed position, with both lens housing 30 and device cover 10 in position to cover the camera lens (not shown) . In this closed position, device cover 10 protects the camera lens from dirt or other damage.
• FIG. 4 shows the lens attachment of the present invention in its partially open position, with device cover 10 flipped up and lens housing 30 in place to cover the camera lens.
• device cover 10 may function as a sunshade, and be rotated about frame 20 to a desired position.
• both device cover 10 and lens housing 30 are shown flipped up relative to frame 20.
• the lens attachment functions as an adjustable position sunshade for the camera lens. It also pivots the lens element 50 away from the optical axis of the camera lens.
• device cover 10 and lens housing 30 are shown separate from each other and frame 20, in order to more clearly illustrate possible mounting locations for magnetic pieces 60. The attractive forces provided by magnetic pieces 60 aid in maintaining device cover 10 and lens housing 30 in the desired positions.
• additional sunshades or side covers 12 may be seen.
• Such additional sunshades or side covers 12 may be coupled to frame 20 by pins 80, to enable the side covers 12 to be positioned as needed to function as a sunshade.
• Extendable panels 100 controlled by guide pins 110 and guide slots 120, may be coupled to the side covers 12 to provide greater ability to shield the camera lens from ambient light.
• the guide pins 110 and slots 120 permit panels 100 to extend as needed, thus enhancing the sunshade effectiveness.
